Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To enhance tracking control pull-in performance without always widening a tracking control band by raising a gain of a D signal component generating system of a PID control system during the time from immediately after operating a tracking control means to control of a tracking control system. SOLUTION: At the time of operating the tracking control, a terminal (a) of a microcomputer 201 is made to be H level to operate switches 133 and 139 to connect with their respective terminals (b) and (a). Consequently, a digital filter 204 is released from its clear state, and a focusing lens 103 is driven in accordance with a TE signal. The level change of the terminal (a) from L level to H level is detected by a timer 209 to make its terminal (b) H level during a prescribed period of time from the point of this changing time. After a lapse of the prescribed time, the gain of the D signal component generating system becomes a normal gain. Consequently, the normal tracking control is carried out. In other words, the control band is widened during the prescribed period of time, thus enhancing the tracking control pull-in performance.

Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To enhance an efficiency of aligning by setting and storing mark positions, deviations and a plurality of allowable values of a material to be treated and a screen according to a type of the material as a calculated results of the deviations of the material and the screen, comparing the deviations with the allowable values, and deciding an aligning result. SOLUTION: In the case of seeing, for example, from a final product, a base A with a sufficient allowed value A takes a time a as an aligning time, and a base B decided with a sufficient allowed value B and sufficient with further lower accuracy takes a sufficient aligning time b. Thus, the aligning time can be shortened, and a printing tact time can be shortened. Thus, since an operator sets the allowed value of the aligning accuracy to each type of the base to be printed and stores it in a base print information unit. At the time of aligning, the value is compared with that of the corresponding information unit, an optimum time responsive to the base can be set, and the printing tact tank can be optimized according to the base.
